How to Prepare for a SOC 2 Report: A Readiness Assessment Guide

Written by Haelyn Seo, CPA.

If your organization handles customer data, clients expect proof that their information is safe. A SOC 2 report provides that proof. But jumping straight into an audit without preparation is one of the most expensive mistakes organizations often make. A readiness assessment gives you a clear picture of what’s working, what’s not, and what needs to happen before the audit begins.

In short: The most effective way to prepare for a SOC 2 report is to start with a readiness assessment. This process helps you define your scope, identify gaps in your internal controls, align with the COSO framework, build a comprehensive System Description, and ensure you have audit-ready evidence before the formal engagement begins.

What Is SOC 2 and Why Does It Matter?

SOC 2 (System and Organization Controls 2) is an attestation framework developed by the American Institute of Certified Public Accountants (AICPA). It evaluates whether your internal controls meet the SOC 2 Trust Services Criteria (TSC), which include:

• Security: Protect systems and data from unauthorized access.
• Availability: Ensure systems are available for operation and use.
• Processing Integrity: Guarantee data is processed accurately and timely.
• Confidentiality: Safeguard sensitive information from disclosure.
• Privacy: Protect personal data according to commitments and regulations.

All SOC 2 reports will include the Security category as a baseline. Inclusion of the other categories will depend on the commitments made to customers and the interests of your report readers. A benefit of this framework is that it allows for the inclusion or removal of categories as organizations grow and change.

SOC 2 compliance isn’t legally required. However, it’s become a baseline expectation for many enterprise clients and a prerequisite for winning larger contracts. A clean report is a signal to the market that your organization takes security seriously and can be trusted with data.

SOC Type 1 vs. Type 2: Which Report Do You Need?

A Type 1 report evaluates whether your controls are properly designed at a specific point in time. A Type 2 report tests whether those controls operated effectively over a defined period, usually between three and twelve months. A Type 1 report confirms that your controls are in place, while a Type 2 verifies that your controls work consistently.

If you’re new to SOC, the best practice is to start with a Type 1 report to establish a baseline, then move to Type 2 for ongoing assurance.

How to Prepare for a SOC 2 Report

Step 1: Define Your Purpose and Scope

Your first step should be to understand your organization’s needs for a SOC 2 report. Is it a client requirement, a market entry condition, or a competitive differentiator? Then, identify which systems and services are in scope and which TSCs apply. While TSC Security is mandatory, the remaining criteria depend on your business model and the commitments you make to customers.

The best practice is to document your scope early, as an unclear scope is the leading cause of delays and audit overruns.

Step 2: Conduct a Readiness Assessment

A readiness assessment is the rehearsal that prevents unwanted surprises later. It identifies gaps before the formal audit by reviewing your policies, procedures, and technical controls. It also validates your System Description (step 4 below), which covers your services, infrastructure, data flows, and third-party dependencies. Finally, it maps your controls to the applicable TSC, so you can see exactly where you stand.

Don’t skip this step. Many organizations fail their first readiness review because they underestimate the amount of work involved.

Step 3: Build Strong Internal Controls

SOC 2 readiness is about operational discipline, not just documentation. Controls should be part of daily workflows, not added just before audit time. Effective SOC 2 programs align with the five core components of the COSO Internal Control Framework, which together structure how controls should be designed, implemented, and sustained.

Key components include:

• Control Environment: Establish the “tone at the top” by defining expectations for security and compliance.
• Risk Assessment: Identify and assess risks to security and business objectives.
• Control Activities: Establish the policies and procedures to mitigate risks.
• Information & Communication: Ensure the necessary information is shared throughout an organization to support internal control.
• Monitoring Activities: Evaluate the effectiveness of security controls.

These five core COSO components form the foundation for SOC 2 controls. While the specific controls selected vary by organization, they are typically implemented through the following operational areas:

• Identity & Access Management: Enforce least privilege and MFA.
• Change Management: Document and approve all system changes.
• Incident Response: Maintain tested procedures for security events.
• Vendor Management: Review subservice organizations and their SOC reports.
• Risk Assessment: Conduct annual evaluations and mitigation planning.

Step 4: Develop a Comprehensive System Description

The System Description is the backbone of your SOC 2 report. It gives auditors a clear picture of your environment by documenting:

• The services you deliver.
• The hardware, software, and network infrastructure supporting them.
• How data flows through your systems.
• Third-party vendors and their roles.
• Policies governing security, availability, and confidentiality.

An incomplete or inaccurate System Description can lead auditors to question your controls, expand testing unnecessarily, or delay the report. A strong one keeps the audit focused and avoids costly surprises.

Step 5: Prepare Evidence and Documentation

Auditors need proof your controls work, which means finalized policies and procedures, accessible system logs and monitoring reports, and documented evidence of periodic reviews and remediation. For Type 2 audits, evidence must demonstrate that controls operated effectively across the entire reporting period, not just at a single point in time.

Common Pitfall: Performing Controls Without Standardization

The scenarios below use a user access review control to illustrate a common SOC 2 pitfall. In both scenarios, the company performs the review. However, one scenario results in a deviation in the SOC 2 report, and the other scenario results in a clean opinion. The difference between the two scenarios is not what was done; it’s how the control was designed and documented, which is a key consideration for audit readiness.

The Control

The example organization has a control stating, “User access reviews are completed by the IT department on a quarterly basis and are approved by the respective system owners.”

Scenario 1: Activity without Standardization

When implementing the control, management assigns responsibility to the IT department, but they provide little direction on how reviews should be performed, documented, and approved. There is no standard process, no required evidence, and no defined review format.

At audit time, the auditor requests supporting evidence to verify that the user access reviews were completed. The IT department confirms that reviews were performed, identifying partial evidence for one quarter. Management insists that reviews for the remaining quarters were completed but is unable to produce consistent supporting documentation.

Auditors cannot rely on verbal confirmation alone, as prescribed by SOC 2 auditing standards. Because the organization can’t demonstrate when reviews were completed, who performed them, or what was reviewed for the other quarters, the auditor cannot provide an opinion on whether the control operated effectively throughout the reporting period. As a result, the control is reported as a deviation in the SOC 2 report.

Scenario 2: Standardized Control Execution

As in the previous scenario, the IT department is responsible for the access review. This time, however, they create a standardized process for executing and documenting access reviews. The process includes the following:

• All access reviews are initiated through the ticketing system.
• Reviewers are required to follow instructions to ensure sufficient review coverage and document their findings in the organization’s ticketing system.
• Once the review is complete, the ticket and supporting files are reviewed and approved by the system owner.

At audit time, the organization goes directly to their ticketing system and exports the supporting evidence. The auditor is able to validate when the review was completed, who completed the review, and what was reviewed. The auditor can provide an opinion on whether the control operated effectively, and as a result, the control is reported with no deviations in the SOC 2 report.

Key Takeaway

Performing an activity is not enough: organizations must design controls so the activity is executed consistently and is supported by audit-ready evidence.

How Timing Affects Type 2 Reporting

Timing is another key aspect to SOC reporting. In a Type 2 report, auditors will test that controls are operational throughout a pre-selected period of time. Ideally, controls are in place and operating for the full reporting period; however, this is not a strict requirement. In cases where a control is implemented partway through the period, auditors will only test the control for the portion of the period in which it existed. This provides organizations with the flexibility to demonstrate progress without delaying reporting.

Why Early SOC 2 Planning Pays Off

From our recent SOC 2 engagements, one theme stands out: early planning pays off. Organizations that define scope upfront, maintain version control on workpapers, and invest in readiness assessments experience smoother audits with fewer surprises. Organizations that don’t define scope at the onset face bottlenecks and increase their risk of receiving a qualified opinion.

SOC 2 readiness isn’t just about passing an audit. It’s about building a culture of security and trust. Start with a readiness assessment, close gaps early, and make compliance part of everyday operations. When you do, SOC 2 stops being a checkbox activity and becomes a competitive advantage.
